About he often traveling all around the world, weeeeeeeell...I'll only believe when I see it:
Mexico: only two times, one in 2009 (just for an awards ceremony, no gigs) and one in 2016, by Universal Studios (just one gig)
Portugal: last gig was in May 2016, but the one before that was in 2012
South America: so far only one time in 2010, Argentina, Chile and Brazil (I haven't attended any of them btw)
Nia, I understand you, here in Brazil we have a platform called Queremos! (We Want It! in Portuguese), where people ask for an artist and they might come for a show or more (we even asked Mika here, but no news from them so far). Do you know if there's anything like this in Georgia??? If not, create something alike, make some noise so events producers invite Mika to your country

There's a meme of a seal playing sax and from that, another meme was created, called ''Midinight Seal'', where everyday, at midnight, a video of the seal ''performing'' a song is posted on YT and Facebook and today's song (Sepetmeber 17th) was Grace Kelly
